Description
Technical field
The present invention relates to a kind of coating applications more particularly to a kind of regulating devices of coating machine extrusion die, more specifically
It is related to the device for precisely regulating of a kind of coating machine extrusion die lip and back rod gap.
Background technique
Coating is equably to be coated in slurry on substrate in a continuous or intermittent fashion, and wherein extrusion coating method has life
The advantages that high-efficient, at low cost, the accuracy of manufacture is easy to control is produced, print field is widely used in.Extrusion coated technique is by one
Layer or multilayer masking liquid, which are posted after squeezing out from the pressurization of the lip of coating machine extrusion die to from back rod, to be passed through and the substrate of continuous operation
On, to form thin layer.Gap size between coating machine extrusion die lip and back rod determines the thickness of coating layer, this gap
Usually 23um, if tolerance is 2um, gap is also only adjusted between 21-25um.Existing coating machine extrusion die lip with
The displacement carried on the back between rod is driven by two parts, and a wide range of movement is realized by cylinder, and accurate positioning is squeezed by being fixed on
The limited block of die head two sides and the vertical screw thread adjusting means being fixed on crack seat are constituted, and vertical screw thread adjusting means are by vertical
Screw rod and nut composition, as shown in Figure 1, its mode of operation is: the distance for first needing to move down according to coating machine extrusion die lip,
The height for adjusting the prominent nut portion of vertical screw rod pushes extrusion die rod direction of supporting or opposing mobile, until extrusion die by cylinder
The limited block of both sides of head is contacted with the top surface of screw rod, then finely tunes vertical screw rod, reaches extrusion die lip with the gap for carrying on the back rod
Production requirement, as shown in Figure 2,3.Existing this mode of operation there are degree of regulation it is low, safety is poor, stability is poor the problems such as,
This is because: 1, adjust using screw flight the gap of extrusion die lip and back flow roll, since screw pitch is 1.5mm, screw rod rotation
One week 360 °, gap change 1500um, accurately to adjust several microns of minor variations, be difficult control screw rod rotation angle；2,
During accurate positioning, since screw rod rotational angle is difficult accurate control, there are the security risks of lip and back flow roll collision, and
The damage of lip, also implies that scrapping for coating machine extrusion die, and loss is serious；3, when each crack seats against nearly back flow roll,
The limited block of extrusion die two sides and the top surface of screw rod are collided, and the flight pitch of screw rod and nut can be made to generate variation, caused down
The height of the prominent nut portion of screw rod need to be readjusted when secondary operation.
Summary of the invention
To overcome the problems, such as present on, the object of the present invention is to provide a kind of degree of regulation height, safety and stability
The device for precisely regulating of good coating machine extrusion die lip and back rod gap.
In order to achieve the above object, the device for precisely regulating of coating machine extrusion die lip of the invention and back rod gap, packet
It includes cylinder promotion part and is accurately positioned part, cylinder pushes partially double cylinder structures by being fixed at the top of coating machine extrusion die
At, it is characterised in that: the accurate positioning part includes being fixed on the limited block of extrusion die two sides and being fixed on crack seat
Horizontal thread adjust component, horizontal thread adjust component include transverse slider, the transverse direction that is contacted with transverse slider left and right ends
Adjusting screw and the nut for being socketed in adjusting screw and being fixed on crack seat, the top surface of transverse slider and the bottom surface of limited block
For the inclined-plane that the gradient is identical and inclined direction is opposite, so that the upper and lower displacement of limited block can be pushed when transverse slider left and right displacement.
Preferably, in above-mentioned device for precisely regulating, the transverse slider be section be in horizontal right-angled trapezium hexahedron, six
Body inclined one side in face is the top surface of transverse slider.
Preferably, in above-mentioned device for precisely regulating, the top surface of the transverse slider and the angle of horizontal plane are 0.5-1.5 °.
Preferably, in above-mentioned device for precisely regulating, the distance of the transverse slider left and right displacement is limited block upper and lower displacement
80-120 times.
Preferably, in above-mentioned device for precisely regulating, the screw pitch of the adjusting screw is 1-1.2mm.Preferably, above-mentioned precision
In regulating device, the distance of the transverse slider left and right displacement is 60-100mm.
The device for precisely regulating of coating machine extrusion die lip and back rod gap of the invention, with existing regulating device ratio
Compared with having the advantage that
1, vertical screw rod is changed to horizontally movable transverse slider, then by the floor design of the top surface of transverse slider and limited block
The identical and opposite inclined direction inclined-plane at the gradient is pushed transverse slider to move left and right and is come by the lateral adjusting screw of rotation
Change the upper and lower displacement of limited block, so that the distance between cloth machine extrusion die lip and back rod are adjusted, when the top of transverse slider
The bottom slope of portion and limited block very hour, the rotation of adjusting screw by a relatively large margin can only slightly change the upper and lower of limited block
Displacement, is greatly improved degree of regulation.
2, in fine tuning position fixing process every time, it can realize precise positioning, avoid coating machine die lips and touched with back flow roll
The risk hit, safety are greatly improved.
3, when each limited block and transverse slider contact, since transverse slider both ends have screw to fix, limited block longitudinal direction
Impact force does not interfere with the precision of transverse slider horizontal displacement, and stability is greatly improved.
